This mib is based on RFC 1493 with modifications to support multiple bridges, one for each virtual LAN (VLAN), in one physical chassis. The bridge protocol attributes are now in a table indexed by the vLanNumber. The port number used to index various tables is now a virtual port number corresponding to the virtual port defined in the SWITCH-VLAN-MIB." REVISION "9704182200Z" DESCRIPTION "Corrected names to switchBridge because of possible identifier. Corrected the MAX-ACCESS clause for writable objects in the switchBridgeStaticEntry from read-write to read-create. Modified description of switchBridgeStaticAllowedToGoTo. This object is also read-only because it maps to the set of ports in a VLAN. Removed the mib compiler specific extensions into a separate file."
